To (L7/Z whom t may concern:

Be it known that we,-ALERED BODE and KARL BTTCHER, engineers, subjects of the German Emperor, and residents of Benrath, near Dsseldorf, in the Province of the Rhine, German Empire, have jointly invented certain new and useful Improvements in Turning-Shovel Dredgers', of which the following is an exact specification.

Our invention relates to improvements in turning-shovel dredgers, and has for its purpose to provide means for closing the shovels with as much power as possible. uFor this purpose the shovels are actuated by pressurerods, which are so connected to the lower pulley-traverse that these rods work in closing the shovels as knee-levers, thereby obtaining a considerable closing power.

In order to make our invention more clear, reference is made to the accompanying drawings, in whichient device of our invention.

Figure I shows a front view of a conven- Fig. 2 shows a side View. Fig. 3 shows another side view 1n which the shovels are shown in open position.

.ters Patent of. the United States isl. In a turning-shovel dredger, the combination of a frame, with two shovels pivotally mounted therein, a traverse guided in this frame, outwardly directed rods, connected with one end to the shovels and with the other end to the traverse, and means for moving said traverse up and down thereby closing and opening the shovels, substantially as described and for the purpose set forth.

2. In a turning-shovel dredger, the combination of a frame, with two shovels pivotally mounted therein, the front walls of the shovels being upwardly continued over their pivots, a traverse guided by the frame, outwardlydirected rods connected with one end to the upper part of these walls and with the other end to said traverse, and means for moving said traverse up and down, thereby opening and closing the shovels. substantially as described and for the purpose set forth.

In witness whereof we have hereunto set our hands in the presence of two witnesses.
